To all 1071 0127. it may concern.-

Be it known that I, CLINTON D. HYRE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fireproof Sash and Frames, of which the following,when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description sufficient toenable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to metal sash for window and to frames for such sash.

The objects of the invention are to obtain a fireproof sash which may be used, if desired, with an ordinary wooden window-frame, to obtain a fireproof sash which may be used in a fireproof frame of simple construction, and a fireproof sash and frame which are so constructed that they are weatherproof, not liable to get out of order, and durable, and, further, to obtain a fireproof sash and frame wherein there will be no binding in the upward-and-downward movement of the sash and no difficulty in removing the sash from the frame when desired from the inside of the building in which the frame is set, while such sash cannot be removed from the frame from the outside of such building.

In the drawings referred to, Figure 1 is a front elevation of a window-frame embodyingmyinvention. Fig. 2 is a vertical sectional view thereof on line 2 2 of Fig. 1 viewed in the direction indicated by the arrows, and showing, also in vertical section, the upper and lower sash in position in the frame; and Fig. 3 is a horizontal sectional view of the frame illustrated in Fig. 1, on line 3 3 of such Fig. 1, viewed in the direction indicated by the arrows. Fig. 4. is a front elevation of the upper sash removed from the frame, and Fig. 5 is a front elevation of the lower sash removed from such frame. Fig. 6 is a horizontal sectional view of the lower sash on line 6 6 of Fig. 5 viewed in the direction indicated by the arrows. Fig. 7 is a side elevation of a spring forming an element in the sashes respectively. Fig. 8 is a horizontal sectional view of one of the elements illustrated in Fig. 6 separated from the remaining elements illu strated in such Fig. 6. Fig.9 is a like view of another one of such elements, and Fig. 10a like view of the remaining one. Fig. 11 is afront elevation of the element of the lower sash which is illustrated in cross-section in Fig. 8 and which is shown in Figs. 6 and 12 with adjacent parts of the sash. Fig.12 is a cross-section on line 12 12 of Fig. 11 viewed in the direction indicated by the arrows, showing also in cross-section a portion of the frame adjacent thereto. Fig. 13 is a top plan view of the frame embodying my invention, and Fig.14 is ahorizontal sectional view of one side of the frame-- say on line 3 3 of Fig.1viewed in the direction indicated by the arrows. Fig. 15 is a horizontal sectional View on line 15 15 of Fig.4 viewed in the direction indicated by the arrows. Fig. 16 is a front elevation of the upper portion of the element forming a part of the upper sash which remains in the runway of the frame when the upper sash is turned on its pivot, such element corresponding with the element of the lower' sash which is shown in Fig. 11 in front elevation. Fig. 17 is aperspective view of a post forming an element of the lower sash. Fig. 18 is a perspective View of a corresponding post forming an element of the upper sash, and Fig. 19 is a perspective view of the loop of the sash to which the chains or cords of the weights are attached.

A reference-letter applied to designate a given part is used to indicate such part throughout the several figures of the drawings wherever the same occurs.

A is the frame, consisting of the stiles a a, bottom a and top a B B are the sash-cord pulleys.

O is a weight, and D is a cord or chain attached to the weight 0 at one end and to the loop E at the other end. Cord or chain D passes over the pulleyB-in the ordinary way.

F, Fig. 2, is a removable part or portion of the frame A for the purpose of obtaining access to the weights 0 C, respectively.

The sides a a of the frame'A when made of metal consist of two strips (1 0. of sheet metal, bent up into substantially the form shown in cross-section in Fig. 14 to obtain the runways G H for the upper sash I and the lower sash J to run, respectively, and to obtain a partition between the sash-weights O C in frame A, and also to obtain an anchorplate, by means of which the frame may be well secured in a brick or stone wall. The edges of the strip a" are bent, as at a a, 'respectively, and the edges of the strip a are bent, as ata (1 so as to interlock when slid together. The strip a is also bent at a a a ,.and a to obtain the partition a a and anchor at a. The strip 0, of the sides at a of the frame A may and preferably does extend from the extreme lower end of such frame A to the extreme upper end thereof, as is indicated by the broken lines in Fig. 1. Upper sash I travels in runway G when raised and lowered and the lower sash travels in the runway H when raised and lowered.

The top rails g g of the sashes I and J and the bottom rails g g of such sash consist of a single strip of sheet metal bent up into substantially the shape illustrated in Fig. 2 of the drawings. The stiles of such sash are made of a plurality of strips of sheet metal bent up substantially as illustrated in Figs. 6, 8, 9, 10, 11, 12, 15, and 16 and the additional parts, which are illustrated in such figures and the additional Figs. 7, 17, 18, and 19.

K is a sheet of glass in the sash.

L is a bent-up strip of sheet metal by means of which, in the manner hereinafter set forth, the glass K is retained in the sash.

In Fig. 7 is shown a side elevation of fiat metal spring M, which is interposed between the element N (shown in Fig. 8) and the element 0, (shown in Fig. 9.) SpringM is preferably attached to element 0, as by clip m andrivets 'm/ m. The element N of the lower sash J travels in the runway H and is bent up to obtain the parallel sides 92 n and the longitudinally-eXtending channel '12. (See Fig. 8.) The sash cord or chain loop E is attaohed to this part N in the channel at, as is shown in Fig. 8, and the sash cord or chain D lies in such channel. The element 0 (see Fig. 9) is bent up to obtain the longitudinally-extending channels 0 O,in which channels the parallel sides 11 n of part N loosely fit the sides or faces 0 0 which are adjacent to the sides of frame A and the sides or faces 0 0 which are turned over, as at O 0 onto corresponding faces of the element P, to attach such parts 0 and P together to form, when taken in connection with part N, the stile of the sash. The part P is bent up to obtain the face 19 and the shoulder p, against which the glass K is forced and held by strip L, and the longitudinally-extending channel 19 ,in which channel one edge of part L extends, as is shown in Fig. 6, to maintain the strip or part L in place in the sash, and the faces or sides 19 over which the face or side 0 is turned, as heretofore described, to hold parts 0 and P together. Parts N and P in sashes I and J are constructed alike, except that the longitudinally-extending rib n in the sash I, which is curved on its outer face, as is shown in Fig. 15, is used in place of the channel n, so that the additional element or part Q may be placed in runway G and pivotally attached, as will be hereinafter described, to

the sash, thereby permitting the upper sash to be swung open.

The spring M, interposed, as described, between the parts N and O, tend to force the part N of the lower sash into the runway H, and in order to withdraw the sash from the frame A, I provide means to draw element or part N back from the frame and against the part 0, with the sides 12. n well in the channels O 0'. To effect the foregoing, I attach the screw-threaded hollow post R to part N, as by the rivets r 4, through the base of such post, and I extend the screw S through hole S (see Fig. 11) into such hollow post. (See Fig. 6.) The element N can be retracted by means of the screw S against the resiliency of the spring M, so as to be entirely out of the runway H, at which time the sash can be removed from the frame, or such element N can be retracted to obtain any desired friction between such element and the frame.

The part Q of the upper sash is bent up to obtain the faces q q in the runway G and also to obtain the recess q, (see Figs. 15 and 16,) in which recess the sash cord or chain D may rest, such sash-cord beingattached to the loop E, which is riveted to the part Q. The part or element Gis formed up to obtain the curved longitudinally-extending groove g corresponding to the rib n on part N of the upper sash.

Topivotally attach the upper sash I to part Q, I secure the socket T to part Q, as by the rivets i i. and place the hollow post U, having the flange u thereon, on the screw S, so that such hollow post will extend through a hole corresponding in cross-section therewith in part N and into the socket T. The hollow post U cannot turn because of the flange u, and so when the screw S is turned such hollow post is moved longitudinally on the screw to engage or disengage with the socket T. The upper sash is turned on the hollow post U by such post turning in the socket T.

By placing the nut S on screw S the spring M may be dispensed with, if desired. By placing a nut S on screw S of the lower sash the spring M may be dispensed with also.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a fireproof sash, the combination of rails and stiles, such stiles comprising, respectively, a plurality of pieces, one of such pieces consisting of a sheet-metal strip bent up to obtain a shoulder against which the glass in the frame abuts and means to hold glass in the sash against the shoulder, another of such pieces bent up to obtain longitudi nally-extending channels on the outer face thereof, such named strips joined attheir edges, and an additional strip bent up to obtain parallel edges fitting loosely in the longitudinally-extending channels and to provide alongitudinally-extending channel for a sash ICC cord or chain, and means to determine the relative position of the additional metal strip and the metal strip adjacent thereto; substantially as described.
